We all do that. We compare our motion to the motion of the vehicles
in the street, and make our decisions accordingly. The fact that we
call that comparison of motions 'time' proves that it's just an
intellectual concept. That's how we came to invent time. We took
what we believed to be a regular, predictable motion, and compared
all other motions to it, and we pronounced it 'time'.

The metric expansion of space can not exceed C, but even if the
expansion is at C we could not have calculated the beginning of time
or the big bang correctly because some light would never reach us to
judge red shift correctly for proper dating of the universe if space
time is expanding at c in all directions its like running on a tred
mill going in the oppisite direction if its moving at C and your
moving at C you never reach your target

It isn't that far off from the dot on the oscilloscope
screen that can be made to "move faster than c." Of
course the dot isn't moving at all, the beam is
repointed elsewhere. Similarly "space" can be filled
in in a way that makes things appear to move apart
at rates greater than c while they're actually moving
at rates lower than c.

So is the imposition of new space between galaxies the
same as relative motion? Given that attraction between
bodies, and clusters of bodies, decreases as the square
of the distance, imposing new space between two galaxies
has such effects.
